I'm a student in the States and I am needing an update tutorial site for abaqus. I've read throught this site, but a few of the sites I've looked at are 3 and 4 year old tutorials. I'm looking for help with engineering solids, for car and motorcycle parts . Any suggestions for a good tutorial would be helpful. Thanks

I doubt the kind of learning that you need can be provided via comments here, and that you will get anything complete to your specific needs. It is better to apply to some training, either online or offline. A simple search results for abaqus training point to Simulia Services website. Here is a list of all available courses from them:

Noel,
Abaqus is a comercial package and its cost depends on where you intend to use e.g., Industry, University, Research centre etc. As far as I know, there is no way to legally get a trial version of this software for free. In any case you should consult Abaqus directly.

Hello, IMechanica's mate, you mentioned cohesive zone model, i use this kind in my studies of initiation and propagation of cracks near a weld joints, i want to use ABAQUS to simulate these behaviours, please can you fit me in this field by giving me some advises. thanks

Hi,could you please give me an idea how to apply cyclic loads in abaqus??Material is aluminium,frequency - 5hz,No. of cycles- 25000,Max-Min loads : 25KN - 2KN??Been struggling to figure this out for a long time.

Hi mam. My nameof is taj pursuing my masters in glasgow university. I am designing a product for a company which consist high density poly ehtylene and poly urithiene. I want to do load analysis on that product is it possible with abaqus. I dont know how to use abaqus can u plz guide me regarding this. Or any other software which you can recommend for this problem.

hi this s arun from in IITMadras india,am doing shell modeling of aluminium plates in abaqus 6.9,want to give the values of continum shell section and attached the pic for your refernce.please help me..

1-4 CAE Example.pdf There is this example in the abaqus help file also you can find more complex tutorial in the help file. I need simulation techniques about Self piercin rivets. Is there any body here who know self piercing rivets simulation in Abaqus...

Sorry that I have no experience on simulation of self piercing rivets in ABAQUS. If you just search "rivet" in ABAQUS Documentation you can find out Tutorials-->Getting started with ABAQUS-->C6 has a related example. Good luck.

Can you tell me, how to select the cohesive element properties. The model which one prepared, I assume arbitary values of cohesive element properties. You can send me reply on my email as well. Its vcvikas@gmail.com

Iam a ressearch scholor from IITM,I would like to know procedure that,how one can model particulate metal matrix composites (wherein reinforces particles of different sizes,orients in different directions in the metal matrix) using either ABAQUS CAE or ANSYS.

I am a brazilian student and I am learning Abaqus by myself, but Iam with some problems. I need to model a composite material but I have not had success. If anybody now Abaqus tutorial for composite material I will be very greatful.

i am simulating a coupled temperature-displacement of composite in ABAQUS/. does anybody have some experience on coupled temperature-displacement simulation of composite please do me a favor, and give me some suggestion.

When you create any model in CAE, it does not create *.fil by default. If you want *.fil file after analysis, you need to enter (*NODE FILE) or (*ELEMENT FILE) line manually in your input file. You need to enter the node set or element set(whatever u want) in that line and data line will include the variables, you want to write in the *.fil file.

You can look at *Node File section in ABAQUS keywords manual if you need more details.

I want to define an special Behavior (Super-elastic ) for ABAQUS,and I tried to Link my UserMAterial routinr (UMAT) to the program but it doesn't identify my Fortran I don't know why? How can I do that

Have you checked if the right compiler and options are being used in
the environment file? Also, try to run your model with some standard
UMAT/VUMAT (as be the case) provided by abaqus. This might help you
narrow down the problem.

Thank you for the documents you have linked. I have a student version of abaqus and i effectively needed this type of document to understand a certain number of things. There are still options that are not obvious for me, but i think i am in the good way.

I was wondering if you had a tutorial concerning crack introduction in a 3-D sample. I would like to have a force representation in function of the mesh size. I don't know how hard a such representation is.

Dear Sir, I would like appreciate to provide me by a various types of abaqus tutorials that are related to dynamic simulation. My research field is in the erosive wear of matewrials. Thanks in davance .

Mr. Al-Bukhaiti,
Consult the abaqus documentation for a variety of tutorial problems. If you are working on a unix/linux system, then type "abaqus doc" on the command prompt to go to the documentation. Alternatively you can search on Google for "abaqus documentation" for a lot of links. I found the following link:http://lcadm.rrzn.uni-hannover.de:2080/v6.6/

If you are interested in simulating wear using Abaqus, then you can refer to my papers/PhD thesis (http://vishwanath.hegadekatte.googlepages.com/curriculumvitae) which deals with wear of ceramic micro components. Also you will find there a review of the literature in this field. Most of my work is concerned with sliding wear, but may be useful for you.

I am working on finite element formulation of thermopiezoelectric shell element. i want to incorporate the element in Abaqus software as a project work. i would like to know how to add the new element in abaqus.how can i add? Pls do help

hi, my name is Paul I´m doing a masters degree in Civil engineering, it´s my first time to try finite element method in abaqus, use others softwares before, all the examples that i saw the help of the program are really complicated, could some send me a procedure o tutorial to do something like a a simple beam or a cantilever beam with four elements (1D, 2D Beams elements) whit one concentrated load and another distributed load, to really understand how the program works, I really y need your help, well, best regards for all of you and good bless you, take care.

sorry if i misspell something I´m from Bolivia a speaking Spanish country

I'am a French student, and I have to work on a student project with Ansys of which the aim is to know the pressure (during time) in a compressible fluid layer impacted by a cylindric rigid body having a constant velocity.

Do you know if it is possible to solve this problem with CFX/CFD Flotran, or if I have to explore an other way to solve my problem? Has somebody experience in this domain (impact, fluid), and could help me?

I am modelling composite structure consist of concrete slab on I-beam, I not sure how to define the 'contact' between surfaces of the sections. any good/simple example (*.inp or *.cae) that i could refer to? so that i will know how/when/where to apply the 'contact' function. please advice. thanks.

I am research scholar and recently working on machining of FRP composites. I am in need to study laser cutting process using ABAQUS simulation for one of the problem. Can any one give me idea about how should i approached it with ABAQUS? Beause that will help me to reduce my plenty of time instead of walking in the dark room.

i try to solve stick-slip problem by abaqus 6.5-1, when i enter to interaction property manager and choose the penalty and toggole on slip rate, the table appear, but the my problem is that, abaqus didnt accept negative value under slip rate becuase just i press on ok that message apear for me (allowable slip rate must be greater than or equal to zero)

so the question is who can i enter negative value to slip rate (relativ velocity)table?

can anybody tell me how to model piezoelectric composite beam in ABAQUS using plane stress element? which section should i creat? solid homogeneous or composite shell? if i creat composite shell section..problem is that it can be assigned to 2-d shell and if u creat solid homogeneous section i m not gettig correct results.

I work about Modelling and digital simulation of the structures fissured under residual stresses, I have the problem to calculate the J-integral when I have in initial condition residuel stress, because Abaqus (6.5) define that

Initial stresses are not considered in the definition of contour integrals. Therefore, contour integral calculations for analyses including initial stresses in the regions used for the contour integral calculations will not be correct

I have many others problems see: Modelling and digital simulation of the structures fissured under residual stresses

i want to work in simulation in machining.is it possible to anyone to send file about learning that and help me. i really need to do it but i am confiused and i dont know what is the start point? . thank you.

I wanna model a 3D composite cantilever beam. My model is 3D, but I use shell element for the section because composite is just defined by shell element. So I can't assignment this section to my model. I'm very glad if you could give me some advises.

I do thank you for your tutorials. But as i have tried the CAE example and i just manged to let work i tried to do my own model by creating part and i wanted to divide it but i did not find any help neither in simuli or tutorial or any other source to guide me on what i want to do basically. I hope if you can help me by emailing me so i can ask you directly please.

I am doing my PhD at the Technical University of Munich (Germany)
and I want to simulate the structural effects of work pieces due to the thermal influence
of manufacturing processes like laser-beam-welding, laser-beam-cutting or
friction-stir-welding. Unfortunately I am more or less a beginner in ABAQUS,
but perhaps you can give me an advice how to start (a special tutorial for
thermal problems) or if it’s possible to simulate these kind of problems at all.

I think FSW is quite different from laser beam welding. Although both of them are joining process, the mechanism of FSW is far away from the traditional arc welding. So before your start, please decide which branch you should choose because both are not so easy to study. For FE simulation, I only carried out FEM calculation of arc welding, such as TIG, MIG and Laser. I highly recommend you to read Goldak's first paper of double eclipsoid welding pool model:COMPUTER MODELING OF HEAT-FLOW IN WELDS, METALLURGICAL TRANSACTIONS B-PROCESS METALLURGY 17 : 587 1986. That paper is a classical work.Another review is also good: Modeling of fundamental phenomena in welds,T Zacharia / J M Vitek / J A Goldak / T A DebRoy / M Rappaz / H K D H Bhadeshia,Modelling and Simulation in Materials Science and Engineering,3 (2), p.265-288, Mar 1995.

I dont know if the newest version of ABAQUS provides the Goldak model or not. But another FE software MSC.MARC has already succeeded in implementation of Goldak model as GUI module. Anyway you can implement the model easily using subroutines.

FSW is still very difficult to model, because the FSW is not simply melt and solidification process. Dynamic recrystallization taks place dramatically in FSW. I think the FE simulation of FSW is much more difficult than arc welding.

I'm not sure what kind of problem you are interested in, but from what you described, I think your work may be related to residual stress/strain after welding or joining process. I think it is very challenging problem because of the highly nonlinear material properties and coupled phenomena. Good luck.

I`m alireza, iread your post, I am working on simulation of arc welding process and I use ABAQUS software. if it is possible for you, please send me two following paper that you mentioned to those in your post:

Hi, everyone! tanks for your attention! I am using ABAQUS for module FSI, during analysis, I get the error information:

The ratio of deformation speed to wave speed exceeds 1.0000 inat least one element. This usually indicates an error with the model definition. Additional diagnostic information may be found in
the message file.

Please am a complete novice with abaqus.i've read a couple oftutorial about it and it's not really going through.i need the room to supply me with free version of the software and some biginners tutorial. Ineed abqus for my future research work on friction composites.

I am sajib.donig my unedrgrad thesis "strenghtening beam in flexure in two point load" using ABAQUS 6.4.

I got results but the beam analysis shows more stiff behaviour...a lot more than exp results.

i used correct E value. for beam 200X300X3000mm i used mesh size 25X25X25 mm,used t3d2 as steel and shell elements as FRP layer.i modelled 1/4 th of the beam and took advantage of symmetry.i also used rigid element to to apply load in two rows.and supported the beam by restraing 3 line of nodes along width in DOF 2.

I am trying to make a shell model of a rectangular plate and need the part in the yz plane (I will eventually use the mesh coordinates, which need to be in the yz plane for another program). However I can't seem to draw in this plane, i can only do it in the xy plane which is the default? (The part has to be a 3D shell). Can anyone help? Thank you.

excuse，can you tell me how to handle the promble when i create an iteraction between two solid parts, and it cause the problem of hard to convergence.

the warning is:

I am reza, student of civil engineering, marin structure in master's degree. nowdays I am invole in a simulation of piles and soil surrounded.I work with abaqus 6.7, and I've use3D elements for piles. I want to obtain the bending moments of the piles, but I don't know how I can get it.It's my pleasure if anybody help me.

I hope you are fine and am really impressed by the work you have done and are continue to do. I am currently working on Abaqus 6.9 and trying to solve a contact problem. I have completed few applications in Abaqus very simple ones that include stress analysis of beams and relative simple structures. But now that i have move to contact analysis, I am struggling to make contact between two simple bodies like a 2D model. I use a plate and place a block on top of it and try to make ineteration between the two but no luck

I was hoping if you or any one can help me in this regard with a simple contact analysis tutorial or guide me where i am worng i will really be grateful.

Iam modelling and analysing a simply supported RC slab with ABAQUS CAE through Concrete Damaged Plasticity. The results show poor curve beyond the elastic region. The load vs central deflection graph shows very low curve at plastic region, which is far away when compared to experimental test result. I have tried many options for tensile behavior but still give poor results. I have modeled concrete material using C3D8R elements and T3D2 Truss elements for steel reinforcement which are embedded into concrete.

Please let me know what is the ideal data or equations or expression to relate the tensile behavior of RC Slab.

And does anybody have the document <<Analysis of composite materials with abaqus>>

I have confronted to errors that I dont know how can I resolve theme, as follows:

The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoRotInert have no rotary inertia associated with them and the rotational degree of freedom of the reference nodes is not restrained. Either rotary inertia must be defined at the reference node or the rotational degree of freedom of the reference nodes must be constrained. See the status file for further details.

and

The rigid bodies with the reference nodes contained in node set ErrNodeRefNodeNoMass have no mass associated with them and some degrees of freedom of the reference node are not restrained. Either mass must be defined or all of the translational degrees of freedom must be constrained. See the status file for further details.

I’m trying to model a reinforced concrete beam using concrete

hello
I want to know:
the problems of cracks, and their choice of propagation direction!
1) is there a method by XFM can calculate the integral J (KI and FIC ...)?
2) what are the procedure?
and thank you, my dear scholars?

iam running a dynamic/explicit anlaysis with an
allocated memory of 8GB in 20 GB ram. after some time the
analysis got an error saying that
"Abaqus/Explicit was unable to allocate sufficient memory during the analysis. Please check the memory setting in the .env file or the memory usage in the .use file if files were available.You can use command "limit" or contact your system manager to increase the datasize for the analysis. If the problem could not be resolved, please report the issue to local office."

i am using 64 bit windows xp system. how can i get rid of this problem. which .env file has to find to make over this problem?

I am interested in using beam element in abaqus and define the stress
resultant- displacement nonlinear curve ( Axial-displacement,
Moment-curvature, torque-twist angle), could you please guid me , how i
can define these curves for beam behaviour?

I am Swapnil student of VJTI India, doing project in "Measuring stress relief in concrete due to Incremental core drilling". For this I have too model a column in which a core will be drilled in a structural element. I wanted to know how I can analyse a model which is continuously remain loaded during the coring process and will give results in terms of stress/strain at specific increment of coring procedure.

For. e.g column is loaded for a certain load and is having certain stress level, i'll remove a increment of 75 mm diameter of 5 mm thickness and see the effect on stress in column, i'll repeat this procedure for more number of increments successively in co relation with previously obtained results.

Use can use XFEM. There is a tutorial that you can follow. Google "Matthew Pais XFEM"

I have modelled using XFEM but does anybody know how to model a crack using conventional FEM. I tried using contour integral but it does not work. When I try to create a crack using contour integral I have to select a crack front and tip, but cannot.

i performing an analysis for fatigue life prediction in ABAQUS 6.10. But i m having some difficulties understanding the working of direct cyclic step. i dont understand that what are we supposed to write of increament size(initial?,minimum?,maximum?) do i need to know fouirier transformation? what is damage extrapolation constant?
can anybody help me out on these things?

I want to model underwater explosion in Abaqus. there is an example in abaqus help by the name of "9.1.3 Response of a submerged cylinder to an underwater explosion shock wave" which is very similar to what I'm trying to model. the problem is that i apply incident wave(planer/spherical/Undex) on the both structure and acoustic medium but i couldn't submit the model and it says " the model attributes wave formulation type must be set when using an incident wave interaction (Int-1 for example)"

Also, I don't understand what you mean by "i apply incident wave(planer/spherical/Undex) on the both structure and acoustic medium".

I suggest you take your problem to your Abaqus customer support person. If you don't have customer support, you will have to be more detailed and explicit if you expect free help from people who are not working on exactly the same problem as you.

Hello
everyone. My name is Alex, I'm a doctoral student at the University of
Salamanca. I am working with an axisymmetric model, steel material. I intend to
obtain the residual stresses produced

(picoseconds). The constitutive model is working: Elastic isotropic, platic
johnson-cook, eos us-up. First work with
Abaqus Explicit Abaqus and then Standart (I import tensions), but Abaqus CAE /
Standart (version 6.13.2) does not allow plastic or Johnson-cook or EOS. To get
"the spring back and therefore residual stress.

Dear Colleagues I want to start some research on the Carbon nano - tubes.In the begining I need to model a CNT in the ABAQUS.I wrote a code for generating the xyz Coordinates of the atoms in a CNT.The problem is that I can not import them in abaqus.Does anyone has an Idea ?
